The Wall Street Journal reported that Frontier Group Holdings, Inc. (NASDAQ:ULCC) CEO Jimmy Dempsey took over permanently in January 2026 after Barry Biffle’s abrupt December exit. Dempsey is now aggressively expanding Frontier to capture the market Spirit Airlines left behind.
Spirit fully shut down on May 2, 2026, ending its 33-year run as the original U.S. ultra-low-cost carrier after two bankruptcies in as many years. Frontier overlapped with Spirit on more than 100 routes, more than any other U.S. airline, and has expanded aggressively into former Spirit strongholds, including Orlando, Fort Lauderdale, Dallas-Fort Worth, Detroit, and Las Vegas, growing capacity 23% year over year.
The airline is also weighing a disciplined purchase of Spirit’s liquidated assets, including Airbus A320 aircraft and scarce slot-controlled airport real estate such as LaGuardia slots and gates at Detroit and Chicago O’Hare. Dempsey has paired this expansion with new revenue initiatives. It includes onboard Wi-Fi and First Class seating, alongside Frontier’s traditional ultra-low-fare model.
Bull Case
Spirit’s exit has created measurable demand for Frontier Group Holdings, Inc. (NASDAQ:ULCC). Second-quarter revenue reached a record $1.3 billion, up 38% year over year, while revenue per available seat mile (RASM) rose 28% and exceeded Frontier’s guidance range. Management expects RASM to increase more than 20% in the third quarter, marking a third consecutive quarter of double-digit growth.
Frontier can capture Spirit’s former market without acquiring the airline. Instead of paying a premium and taking on Spirit’s liabilities, Frontier can selectively acquire valuable assets, aircraft, and scarce airport slots through the bankruptcy liquidation.
Management is prioritizing disciplined growth since Dempsey has emphasized a measured approach to new routes and asset purchases. Better revenue management drives much of the RASM improvement rather than capacity growth alone.
Frontier Group Holdings, Inc. (NASDAQ:ULCC) has set a clear profitability target for the turnaround. Frontier lost $190 million through the first nine months of 2025, but it now expects the airline could return to profitability in the second half of 2026. Fourth-quarter adjusted EPS guidance reaches as high as $0.20 per share.
Bear Case
Revenue growth has not translated into profitability. Despite record revenue, Frontier Group Holdings, Inc. (NASDAQ:ULCC)’s net loss widened to $90 million in the quarter, while first-half 2026 net losses more than tripled year over year to $362 million. So, the Spirit-driven revenue boost has not improved the bottom line.
Higher fuel costs could erase some of Frontier’s pricing gains. Fuel costs rose sharply over the same period, creating an external cost pressure that could offset the benefits of reduced competition if energy prices remain elevated.
Competitors could weaken Frontier’s pricing advantage. Frontier’s executives have acknowledged that rival airlines have started replacing some of Spirit’s former capacity. JetBlue also plans to capture part of Spirit’s former customer base, which could reduce Frontier’s pricing advantage as competitors return.
Frontier must execute carefully to turn the turnaround into sustained profits. The airline needs to convert strong RASM growth into higher earnings while managing new routes and asset purchases. Any weakness in execution could delay its return to profitability.
Hedge Fund Data
Insider Monkey’s database shows Frontier Group Holdings, Inc. (NASDAQ:ULCC) was held by 34 hedge funds in the second quarter of 2026, up from 27 in the first quarter. JetBlue, a rival also positioned to benefit from Spirit’s exit, was held by 37 funds, down slightly from 38.
Conclusion
Frontier has gained meaningful momentum from stronger demand and Spirit’s exit. It gives management an opportunity to rebuild profitability. Still, the airline must overcome high fuel costs, returning competition and ongoing losses before it can prove the durability of its turnaround. The next few quarters should show whether Frontier can turn its revenue momentum into consistent earnings growth.
